With (EP)

With is the fourth mini-album by South Korean singer Nam Woo-hyun. It was released on October 19, 2021, by Woollim Entertainment and distributed by Kakao Entertainment. After releasing his previous record A New Journey (2019) and completing his Arbor Day 2 concerts, Nam enlisted in mandatory military service that October. He completed his duties and was discharged in August 2021. He held two concerts entitled Ontact Concert: Arbor Day On shortly after his return, where he announced his forthcoming project.

Regretting some of his music from previous works, Nam crafted an R&B and pop mini-album. Following a series of photo and video teasers, With and the lead single "Calm & Passion" were simultaneously released. Nam promoted the song by performing it on music chart programs across various television networks. The mini-album peaked at number eleven on South Korea's national Gaon Album Chart and has sold over 25,000 copies since its release.
